Back boxes are usually shipped in large containers separate from the system electronics. If
system electronics containers are shipped with the back box containers, store the system
electronics containers in a safe, clean, and dry location until the back box installation is
completed, and you are ready to install the system electronic bays.
All back box PIDs are listed in Chapter 1.
